What organic compounds always contain?
An organic compound will always contain at least one carbon atom
Best explanation to why organic compounds are more numerous than inorganic compounds?
All organic compounds contain carbons, with each carbon forming four separate covalent bonds, meaning there is great diversity in the possible combinations of atoms to create different compounds
Are the oxygen and hydrogen atoms more stable within the H2O compound or as separate atoms and why?
The atoms are more stable within the compound, as all of their electrons are paired, whereas as within the individual atoms some of the electrons are unpaired and reactive
Which of the following accurately describes the covalent bonding of a carbon atom?
Each of the four unpaired valence electrons of a carbon atom can form a covalent bond via electron sharing with other atoms such as hydrogen and carbon
Which of the following best describes the difference between a saturated and an unsaturated hydrocarbon?
The carbons within saturated hydrocarbons are connected to other carbons by single bonds, whereas at least one carbon in an unsaturated hydrocarbon connects to another carbon atom through a double or triple bond
Which of the following correctly describes the major difference between the straight chain (acyclic) and ring structured (cyclic) hydrocarbons?
Acyclic hydrocarbons have carbons at the end of the structure that bond to only one other carbon atom, whereas all of the carbons in a cyclic structure bond to two other carbon atoms
Which of the following best describes why acyclic and cyclic versions of hydrocarbons contain different numbers of hydrogen atoms?
Acylcic hydrocarbons have more hydrogen atoms than cyclic hydrocarbons, as acyclic hydrocarbons have defined end carbons which attach to three hydrogen atoms
Once you've identified that a compound contains a certain functional group, what do you now know about the compound?
The compound will react similarly to other compounds with the same functional group
Which of the following is true about the number of functional groups a compound can contain?
A compound may either contain many or very few functional groups
Which of the following best describes stereoisomers?
cis-butane and trans-butane are stereoisomers that have different arrangements in space but have the same bonding arrangements
